I purchased this piece some time ago, but have never displayed it as my partner loathes it. I do not like the glaze either, but I found it an interesting shape. If anyone can shed light upon the maker it will be much appreciated. Incised 1976 and the letters T H L****, I cannot make out the last name.

Sorry, excuse my lack of knowledge, I was judging by the weight, I thought porcelain was lighter than earthenware. I think I need to spend a little time educating myself about such matters, I have often struggled to identify the actual material and can safely now say that I know less than I thought I knew before, lol.

Thank you Denby So a stronger material, which from my understanding means it must have a greater density than anything else that is crafted and fired?But what about colour, is this the biggest tell tale of the above vase being porcelain, because the unglazed foot is white? Or is there something else I am missing?

the porcelain clay is extremely dense and the molecules being tightly bonded makes for very strong clay bodies that can be thrown very finely into tableware etc but thickly pottered porcelain is as heavy as pottery gets.Colourwise porcelain is white but can have a turquoise tint to it when fired
